Spiders don’t have any ears.
They don’t have any ear-drums.
And so we thought they couldn’t hear
and only felt their webs strum.
But scientists who’ve scanned their brains
noticed they responded
when squeaky chairs and music strains
from far away were sounded.
Special hairs that wobble when
a soundwave moves the air
means jumping spiders hear quite well
through nerves attached to hairs.
These snoopy spiders listen-in
for buzzing enemies
like deadly wasps that sting and sing
some scary melodies!
